Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example 1, as Figures 1-4 As shown in Figure 8, this embodiment discloses a sampling device for atmospheric waveguide detection, including a mobile box 1, a protective door 13 on the surface of the mobile box, a storage slot 2 inside the mobile box opposite to the protective door, a flow box 21 inside the storage slot, two or more flow pipes 22 and an air outlet pipe 26 on the flow box, a first control valve 23 on each flow pipe to control its on / off state, and each flow pipe is connected to an airbag ring 25 through a connecting pipe 24. The flow pipe and the connecting pipe are connected by threads. The air outlet pipe is connected to the air outlet hole on the mobile box, and a second control valve 27 is provided on the air outlet pipe to control its on / off state. A storage cavity 3 is also provided inside the mobile box, and a suction pump 31 is installed in the storage cavity. The air outlet end of the suction pump is connected to the flow box through a pipe, and the air intake end is connected to a corrugated pipe 32 outside the mobile box through a pipe. An air intake head 33 with a filter screen 312 is provided at the opening of the corrugated pipe.

[0025] When using the device disclosed in this invention, the air pump is started, and while the bellows provides suction, external gas is collected through the suction head. The bellows facilitates the removal of the suction head to collect gas from the desired location. The collected gas is then delivered to the flow box through the outlet. By opening the first control valve corresponding to the required airbag ring, the collected gas can be delivered into the airbag ring. The amount of gas collected by the airbag ring is visible to the naked eye. Once collection is complete, the corresponding first control valve is closed. After manually sealing the airbag ring by pinching its front end, it is removed from the connecting tube to facilitate the transfer of the collected gas.

[0026] After the second control valve is opened, the gas in the flow box can be discharged from the gas outlet through the gas outlet pipe, preventing mixing with subsequent collected gas.

[0027] In this embodiment, the push rod 12 and the PLC control panel 11 electrically connected with the air suction pump are installed on the moving box. The push rod facilitates the movement of the moving box, and the PLC control panel controls the opening of the air suction pump. A universal wheel 17 is installed at each corner of the bottom of the moving box to facilitate the movement of the moving box.

[0028] The protective door is hingedly installed on the surface of the moving box and connected with the moving box through the buckle 14. The protective door can be opened or closed through the buckle.

[0029] As shown in Figures 5-6 , a placing rack 15 is arranged on the top of the moving box, and a placing groove 16 is formed in the placing rack. A clamping block 35 is arranged on the air suction head, and the clamping block can be placed on the placing groove to facilitate the placement of the air suction head.

[0030] As shown in Figure 5 , two or more limiting holes 34 are arranged on the air suction head. A filter screen 312 is installed on a filter frame 36, and an installation groove 37 is formed in the filter frame, which has the same number and opposite positions as the limiting holes. A clamping column 310 is inserted into the installation groove, and both ends of the clamping column are exposed outside the installation groove. One end of the clamping column can be inserted into the limiting hole, and the other end is provided with a handle 311. An installation plate 39 is arranged on the outer wall of the part of the clamping column located in the installation groove. A reset spring 38 parallel to the clamping column is arranged between the installation plate and the inner wall of the installation groove. When the handle is pulled to pull the clamping column out of the limiting hole, the reset spring is compressed under stress. When the handle is released, the reset spring resets and pushes the installation plate to reset the clamping column.

[0031] When in use, the clamping column is lifted by pulling the handle, and the reset spring is compressed under stress at the same time. When the clamping column and the limiting hole are one-to-one opposite, the handle is released, and the reset spring resets and pushes the installation plate to insert the clamping column into the limiting hole, thereby installing the filter frame on the air suction head.
